Optimization Solutions For
Compressors are often run in always-on, hot-gas bypass (HGBP) mode, in order to maintain an extremely narrow dead-band--sometimes +/- 0.5 degrees. This comes at the cost of massive energy consumption. Circular chart-recorders and control panels provide data, but are they really telling you what you need to know? Can they predict a problem before it happens?
NRM’s intelligent controls know when to switch to high-energy, instant response hot-gas bypass operation, and when to back off and return to stable pump-down operation with highly efficient condenser and evaporator cycling for improved temperature stability.
NRM’s web-enabled controls and monitoring platform acts as an extra set of eyes and hands on your refrigeration system. View advanced diagnostics and detailed operating data anytime. Receive real-time alerts before temperatures go out of range. Set custom defrost schedules based on deliveries or load requirements. Access historical performance data for audits and reporting, and optimize temperature performance and equipment life.
Never be in the dark about a mechanical issue again. NRM’s platform keeps you connected to your equipment 24/7, from anywhere. Many mechanical issues can occur when you least expect them, or when you’re not even there to notice them. Evaporator coil icing up on a Saturday? Receive an alert to your phone, schedule extra defrosts from your mobile browser, and resolve the issue. Cooler or freezer door left open? Get an alert and call the onsite staff before it becomes a temperature problem.
Scalable, real-time oversight, tested and proven across tens of thousands of coolers and freezers. Track temperatures, equipment run-times, on/off status, compressor operation, energy consumption, and more. Refrigerant leak detection, lead/lag, load shifting, adaptive defrost, demand limiting, superheat and sub-cooling performance, and custom management strategies can all be easily implemented.
When the energy-efficiency industry thinks refrigeration, they think NRM. Our award-winning solution is multi-faceted—comprehensive smart controls, predictive diagnostics, a web-based platform, hardware upgrades—allowing it to provide unmatched optimization. Across tens of thousands of coolers and freezers, NRM solutions reduce energy consumption by 30% or more.
With unique 24/7 technical support, dozens of service and installation trucks on real-time GPS tracking, automated work-order management and dispatching, NRM is fully equipped to make sure you get the best possible outcome. Our true turn-key approach to implementation, commissioning, training, and post-installation support, means that one company is accountable: NRM. And our ongoing support also allows for continuous training. When roles change or new service professionals need training, we’re only a phone call away.
NRM’s controls are designed from the ground up to be serviceable by anyone. One-button bypass instantly restores the system to pure mechanical control. If the NRM controls fail or lose power, they immediately go to bypass, and come back online with all settings intact. Simple, user-friendly interfaces and operation makes it easy to get state-of-the-art diagnostics without needing to be a computer expert or an engineer. Automated temperature logging eliminates the need for manual recording.

"In our Annenberg dining hall freezer, our compressors were on the verge of burning out, and we would never have picked up on it if not for the monitoring software. Not only did the alert save the compressor, which is a multi-thousand-dollar repair in itself, but potentially a freezer’s worth of product that might have been lost otherwise. We've had the monitoring software for 10 years, and I wouldn't give it up for anything. It is one of the best things I did to save money on this campus."
